Diversinervus Silvestri 1915 

Hosts. Hemiptera  : Coccidae 

elegans Silvestri 1915: 304 

Type. DEZA

Distribution. E (Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Ventura  )

Host/habitat. Ceroplastes brevicauda  , C. destructor  , C. floridensis  , C. rusci  , C. sp., Coccus hesperidum  , C. pseudomagnoliarum  , Drepanococcus chiton  , Eulecanium kunoense  , Gascardia  sp., Inglisia  sp., Marsipococcus proteae  , Parasaissetia nigra  , Parthenolecanium corni  , Pulvinaria floccifera  , P. psidii  , P. urbicola  , Saissetia coffeae  , S. oleae  , S. persimilis  , S. sp.

Remarks. The first effort to import this species (in a Saissetia oleae  biocontrol program) into California was in 1931, but the stock perished in transit ( Compere 1931). Successive importations (from Eritrea in 1953 and Lebanon in the mid- 1960 s) proved more successful, and it was released throughout the state ( Lampson & Morse 1992). Initially, this species was recovered wherever S. oleae  occurred in southern California ( Bartlett & Medved 1966), but later studies found it only established in the coastal region of southern California ( Kennett 1986; Lampson & Morse 1992), possibly as a result of being outcompeted by other imported natural enemies. Lampson and Morse (1992) suggested that D. elegans  can act as a hyperparasitoid, but the detailed studies of Bartlett & Medved (1966) found no evidence of such (although second instar larvae will engage in combat to reduce the number of supernumeraries). Specimens from UCRC are recorded from Aonidiella aurantii  , but I suspect these are misidentified.
